概括
对COVID-19结果的临床预测模型在外部验证时表现不佳. 大多数模型都无法准确预测重症监护室患者的侵入性通风或死亡,这表明普遍性有限.
科学领域:
- 关键护理医学 关键护理医学
- 流行病学 流行病学
- 医疗信息学 医疗信息学
背景情况:
- 临床预测模型 (CPM) 对于管理COVID-19患者至关重要.
- 外部验证对于评估CPM的通用性至关重要.
研究的目的:
- 通过外部验证临床预测模型,预测COVID-19肺炎的ICU患者的侵入性通风或死亡.
- 评估现有的COVID-19预测模型的现实世界性能.
主要方法:
- 单中心回顾性外部验证研究,使用常规收集的ICU电子病例记录.
- 确定了13篇临床预测文章,并在302名COVID-19ICU患者的队列上测试了他们的模型.
- 数据包括2020年3月至2022年2月期间入院的患者,以及德克萨米他治疗采用前的子集.
主要成果:

Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
